Rate Breakdown

Property taxes in Hillsborough County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Hills Hillsborough County

In Hillsborough County, property tax is calculated by multiplying the assessed value of a property by the combined millage rate set by the county, the City of Tampa (or other municipalities), school districts, and special districts such as drainage or fire protection. The assessed value is determined by the Hillsborough County Property Appraiser, who appraises each parcel at roughly 100 % of its market value as of January 1 of the tax year. For residential properties, this value is often the most recent sale price adjusted for improvements, while commercial and industrial properties may be appraised using income, cost, or comparable‑sales methods.

Once the assessed value is set, the millage rate – expressed in “mills” (one mill equals one‑tenth of one percent, or $1 per $1,000 of assessed value) – is applied. For example, if a home is assessed at $250,000 and the total millage rate for the year is 18.5 mills, the property tax bill would be:

• Assessed Value: $250,000
• Millage Rate: 18.5 mills (0.0185)
• Tax Due: $250,000 × 0.0185 = $4,625

Rates can vary each year because each taxing authority sets its own budget and may adjust the millage accordingly. The County Treasurer’s Office publishes the final combined rate annually, and the property tax estimator uses this figure to generate an approximate bill.

Available Exemptions

Florida offers several exemptions that lower the taxable portion of a property’s assessed value. Below are the most common exemptions for Hillsborough County residents:

• Homestead Exemption – Up to $50,000 for primary residences. The first $25,000 applies to all property taxes; the second $25,000 applies to all taxes except school district levies.
• Senior Citizen Exemption – For homeowners 65 years or older with a household income of $31,000 or less; provides an additional $5,000 exemption.
• Disability Exemption – Same income threshold as senior exemption; grants a $5,000 exemption for qualified individuals with a qualifying disability.
• Veteran Exemptions – 100 % exemption for disabled veterans with a service‑connected disability of 100 %; or a partial exemption (up to $5,000) for veterans who served in a combat zone.
• Widow/Widower Exemption – Up to $500 exemption for surviving spouses of a veteran who died in active service.

All exemptions must be applied for through the Hillsborough County Property Appraiser’s office, typically by March 1 of the tax year. Proof of eligibility (e.g., proof of age, income, disability, or military service) is required.

Payment Schedule & Deadlines

Hillsborough County property taxes are billed twice a year. The first installment is due November 1, with a discount for early payment (often 4 % if paid by the first of the month). The second installment is due March 1, with the same early‑payment discount if paid by March 1. If either installment is not paid by the due date, the discount is lost, and a 1 % per month late fee (capped at 18 %) is assessed.

Taxpayers may also choose to pay the full amount in a single payment by the November deadline, thereby avoiding the second installment and any additional administrative processing. Payment options include online through the County Treasurer’s portal, mailed checks, or in‑person at any authorized payment center.

Appealing Your Assessment

If you believe your assessed value is too high, you have the right to file a petition with the Hillsborough County Value Adjustment Board (VAB). The appeal process follows these steps:

• File a Petition – Submit a written petition and supporting evidence (comps, photos, appraisal reports) to the VAB online or by mail by July 31 of the tax year.
• Schedule a Hearing – The VAB will assign a hearing date, usually within 30 days of receipt.
• Present Your Case – At the hearing, present all documentation that shows the market value is lower than the assessed amount. You may be represented by an attorney or tax consultant.
• Decision – The VAB issues a written decision within 30 days after the hearing. If the decision is unfavorable, you can appeal to the Office of the Property Appraiser or take the case to the circuit court.

Successful appeals can result in a reduced assessed value, which directly lowers your property tax bill for the current year and future years, provided no further reassessments occur.
